[Objective]To explore the method and clinical efficacy of non-melting electrode argon arc weld-ing for repairing all kinds of fractured or defective mental restorations. [Methods] Non-melting electrode argon arc welding equipment was used for welding restoration. [Results]The 38 cases of fractured mental restora-tions, 20 cases of defective mental restorations, 12 cases of mental restorations with inadequate proximal con-tact and low occlusal surface and 6 cases of telescope crown dentures were welded and repaired. Retention in-strument was welded on 6 cases of old metal restorations. Clinical follow up and further consultation for 3 years showed the total success rate was 93.9% and 5 cases were failed. [Conclusion] Non-melting electrode argon arc welding is widely used in mouth restoration techniques. The technology is relatively leading. Its clin-ical significance is lower cost of equipment and operation. The method for repairing the fractured or defective mental restorations is simple, and has short time, low cost and high efficacy, so it should be spread strongly.
